there are many ways to drain it, not sure how you would fill it back up though. what do you mean its stripped? like the allen key doesnt turn the bolt, or the threads are stripped?hopefully your fill bolt isnt stuck, this way you could just use a pump to pull the fluid and push in the new right from the fill bolt. im not sure what these look like on 5spd, i know my tranny drain/fill bolt have a copperish ring on them which should be soft metal. sometimes its just a matter of breaking it free. you are using a lot of pb blaster yes? take a flat head and use a hammer to tap around on the copper ring. im not sure if a torch is a good idea there.
